You have options for numbers (PowerPoint users need not apply)

If you must  have a table on your poster, look into what options you have for your numbers. Many fonts have number variants.

Proportional numbers have skinny numbers (e.g., 1) and wide numbers (e.g., 0). Two numbers differ in width depending on what numbers they have. But tabular numbers are all the same width. So decimal places and dividers will line up if the numbers are lined up, as they are in a table.

If you have a table, it only makes sense to use tabular numbers if you can. They are explicitly designed to make your tables more readable! But tabular numbers will only do so if you follow a couple of other good practices:

• Make your numbers right aligned.
• Use the same number of decimal places in each column.

You may also find a couple of other options. numbers can be either lining numbers (all the same height) or oldstyle (with ascenders and descenders, like upper and lower-case letters). That means you have four options for many fonts.

In Microsoft Office, these options are sometimes buried. In Word, open Fonts and then look under the Advanced tab. In some Office components, number options are flat out unavailable. I’m looking at you, PowerPoint! The image in this post is a PowerPoint slide, but the numbers were made in a different graphics program (CorelDraw), exported to a WMF file, and then imported into PowerPoint.

To make things more confusing, which numbers a font shows by default are not standard. In the sample above, Corbel uses proportional numbers as its default, while Times New Roman uses tabular numbers as its default.
